City garden. 4 big containers of potatoes. Dug up all the lovely potatoes, (first earlies) and removed green potato hulm (sp?) I've now put some tomato plants and some petunias in the same compost, and watered with tomorite. Have I doomed my tomatoes or is it better to grow some salad leaves instead?
I am no expert but I think it is best not to use the same compost - as tomotoes are pretty greedy and there won't be much nutrient left in the compost and also, because both potatoes and tomatoes can get blight so using the same compost increases the risk of contamination. Tomatoes can be put in grow bags that are on their ends (rather than 'flat') - the roots get more space to grow this way and the whole set up is more stable so the plants are less likely to blow over.
